There are a few times, mentioned in Mary Shelley's novel Frankenstein, where Victor speaks of his desire to return home.
-First, after he has created the monster, Victor receives a letter from his father. His father is asking him to return to Geneva in order to do a few things.
-"Come, dearest Victor, you alone can console Elizabeth." Victor's father wishes Victor to return home so that he can console Elizabeth given her extreme depression (because of William's death and Justine's charge with the murder).
- Victor wishes to find the creature given he knows it is responsible for William's death.
-Victor wishes to return home so that he can help Justine's case (so she is not found guilty of William's murder).
-Another reason, which appears later in the novel, Victor wishes to return home is that he is worried that the Creature will go after his family since his (Victor's) destruction of the Creature's mate. The Creature, after watching Victor destroy his mate, warns Victor that he will be with him on his wedding night. Victor knows that the Creature's warning is a promise to come after him and his bride.
-Lastly, Victor wishes to return home in order to marry Elizabeth. He has destroyed the Creature's mate and, refusing to ever create another, desires to return home in order to insure his parents' wishes come true.
